IMPROVEMENT 1N BoB-sums The Schedule referred to in these Letters Patent and making part of the sama.

To all whom 'it may concern.U

Be it known that I, Joux KILLEFER, of West Richfield, Summit county, Ohio, have invented certain new and useful Improvements in ABob-Spleds; and I do hereby declare that the following isa full, clear, and exact description of my invention, reference being had to the accompanying dawings, forming a part of this specification, and to the letters of reference marked l thereon, of which dlawingsy Figure l is a side view of my improved boh-sled.

Figure 2 is a plan of the saine.

Figure 3 is a rear-end view of the same, showing the ruriner-standards and axle-pipes in section.

Figure 4 is a cross-section of the runner-standard, and transverse section of the axle-pipe. y

Figure 5 isa transverse section ofthe runner-standard, and cross-section of the axle-pipe.

Figure 6 is a side view of coupling-piece, andside view and plan of coupling-piu, for the coupling between the tongue-roll and runners. l

My invention consists, first, in the novel construction of a runner-standard and axle-pipe, for that class ot' bob-sleds in which the runnersare arranged on axle under the sled-body, said runner-standard being constructed in a seinicircular form, or a U-forni, orany similar fornrwhich would give it" two separate points of attachment on the ruimer, having each of its legs made of a hollow or corrugated cross-section, and having a concave seat formed on it, on which the axlepipe is secured by bolts or their equivalents. The

advantages resulting from this construction are, that' by making the legs of the ruimer-standard of a hollow or corrugated section, a muc-l1 stiffer and stronger standard is obtained with the same material than could' be obtained in the old forni of stamlards,with square, or rectangular, o1 solid round legs; and, by putting the material in this shape, its thickness at any sect-ion is so diminished vas that the standard can readily be made of malleable cast-iron, thus making it much cheaper to manufacture than a wrought-iron standard, and obtaining a better standard for practicalvr use than could be made of connnon cast-iron.

My invention consists, secondly, in the novel construction ol' a coupling for the tongue-roll and runners of a bob-sled, having the ii'ont runners arranged to work on an axle independent of each other, whereby a cheap and strong couplings obtained, which allows of the tongue being put in or taken ont ofl the front bob in a very simple manner.

. To enable others skilled in the art to make and use my invention, I will proceed to describe its const-ruct'ion'and operation.

- The holsters, reach, axles, and runners'in the sled` represented in the drawings are of an ordinary form, and are arranged as shown, the rear end of the reach passing through the hole formed in the rear bolster I and axle, as shown in figs. l, 2, and 3, and being bolted, by side strap-bolts, to the front holster, as shown in figs. l and 2.

being made with its legs of a hollow sect-ion, convex on the upper side, asl shown in figs.' 1,3, and 5, .and having a concave seat formed on its upper side, and at itscentre, to receive the axle-pipe A.v l

/ The ends of thelegs ofthe runneifstandards B are flattened out, and have side' lit nges, between which are .secured the'. runners, as shown in figs. 1 and 3.

The axle-pipe A is Secured on its seat on the standard B by bolts or rivets, as shown, and has t'wo bearing-surfaces formed in it, each ol' a cylindrical form, and one at cach end ofthe axle-pipe, as shown in'fiw. 4, from which it is readily seen that both bearings in the pipe can he bored out, by an ordinary drill, in a very cheap and simple manner.

The axle-pipe is held on the axle by a cap and bolt screwing into the end of. the axle, as shown in figs. l and 3, and the ravcl is bolted on to the pipe A, and extends forward to thc toe ofthe runner, as shownv in 1, 2, and 3.

The draught-chains (l C are fastened, by eye-bolts, to the rear axle, and cxtcnd forward to the sliding reach-collar, and the roar bobrunne.1s are secured at any desired point ou thc reach by bringing the rear bolster and axle up against a .pin inserted in one of the holes in the reach, and thcn sliding the reach-'collar forward until the chains (l (l are drawn tight, when it is fastened by a pin inserted behind it in a hole inthe reach, as sho-wn in ligs.'1 and 2.

f 'lhe toes of the hind runners are united, by chains, to the reach-Collin', as shown in figs'. l and 2, by which the rocking movement of the runners is confined within properlimits.

The frontaxle is pivoted to the bolster by means of a bolt,-F, shown in detached views in lig. 2, which is made witlra flattened end, and is passed up through the laxle and holster, when.` 'it is secured by the slotted washer and key, as shown in lig. 2. y

The coupling-piece l) is made with a circular holo,

having a slot cut at each sidc, as shown in fig. 6, and

is secured to the rave, as shown in iig. 2; 0r, it' preferred, it could be attachedto the ruimer.

The coupling-pins E are made with a flattened heazl, as shown in iig. (l, and are scoured in the ends of the tongue-roll in an ordinary manner.l f

The hole in the coupling-piece l) is of about the same diameter as the pins E, and the iiattened head of the pin E is ot', a-suitable size to pass through the" rlhe rluiner-stamlard B is of the general forni shown,-

turning up the tongue, the pin E can besld into the hole in the .coupling-piece, D, on one runner, when, by bringing the pin E, on the other end of the roll, opposite the hole in the other coupling-piece D, and bringing lthe toes of the runners to the same level, the pins E will be both slid into the pieces D, and the tongue will then be secured in the runner by turning. it down to its working-position.

I am aware that runner-standards with two legs have been before shown; hence I ,marke no claim to such standards, except when constructed with legs of a hollow or corrugated section, and with concave seat for the axle-pipe, as is herein shown. Nor do I claim the axle-pipe, exceptwhen combined with the runnerstandards, constructed as herein shown but What I claim herein as new, and of my invention, and desire to secure by Letters Patent, is

1. The runner-standard B, constructed with legs of geen 4 a hollow or corrugated section, and with a concave seat for the axle-pipe, as is hereinbefore specied.

2. The axle-pipe A, constructed with two cylindrical i
